Radius irule

Needs some help with my irule that we use to load balance AAA UDP traffic. my rule works fine for 1812/1813 traffic but when it comes to 1645/1646 traffic it fails. I'm sure its something wrong wit...

Your code, maybe better formatted:

 

when CLIENT_ACCEPTED {
    if { ([UDP::local_port] != 1645) && ([UDP::local_port] != 1646) && ([UDP::local_port] != 1812) && ([UDP::local_port] != 1813) } {
    log local0. "packet on port [UDP::local_port] dropped"
    drop
    } else {
    set CALLID [RADIUS::avp 31 string]
    persist uie $CALLID
    log local0. "persisted $CALLID"
    }
}

when CLIENT_DATA {
    if { ([UDP::local_port] == 1646) or ([UDP::local_port] == 1813) } {
    set CALLID [RADIUS::avp 31 string]
    set IP [RADIUS::avp 8 ip4]
    if { $IP != "" } {
        table set $IP [LB::server addr] 900
        log local0. "Radius maps $IP to [LB::server addr] for $CALLID"
    }
    }
}

when LB_SELECTED {
    log local0. "Selected [LB::server addr] [LB::server port]"
}

when SERVER_DATA {
    persist add uie $CALLID
    log local0. "persist added for $CALLID to [LB::server addr]"
}
